Abstract
Changes of dye-density in blood after the injection of dye T-1824 were studied in rabbits which have, as stated in part I, experimental disturbance of hemodymanics in heart. It was shown that the time needed for the appearance of maximal dye density after dye-injection was prolonged in accordance with the development of hemodynamical disturbance of heart. This fact means not only the prolongation of mean circulation time but relative increase of the blood which take less part in blood circulation because of its too slow moving. The latter means the iner ease of relative depot of blood. The same conclusion was also obtained by the 2nd investigation i. e. the analysis of mixing grad ient of dye ((Δc)/(cΔt)) which the author proposed in this treaty to use in the investigation of the change of dye density in blood (C: dye density in blood, t: time)
